Last year I took the drone to a coastal town in NSW and thought I would get some nice footage, signs everywhere 'No Drones', I asked why and was told that the coastguard helipad was on top of the hill, we went for a look and there was nowhere a chopper could land, I suspect locals are just sick of irresponsible operators, we can't use them in national parks, the wording is 'no remote controlled aircraft' so I take that to mean I can suspend a Gopro under a kite as it is tethered, I'll wager they will find some way of stopping you.
I was approached once in a national park and asked if I had a drone, I said yes and they said they wanted to confiscate it, I said I would have to home 400km and get it for them, they were not amused but I do enjoyed being a sanctimonious pedant with power hungry minions who do not have the power they think they do.
As for National Parks, the signage, No Shooting, No Fishing, No Camping, No Rubbish, No Stopping on side of road, No driving off road, No open fires, No feeding wildlife, No picking wildflowers, Enjoy your visit.
